摘　　要：热辐射基本规律的演示仪由辐射方盒和红外传感器等组成,可演示方盒温度和辐射表面颜色、粗糙度等对辐射出射度的影响,探究低温热辐射的斯特藩-玻尔兹曼定律和辐射出射度与距离的平方反比关系.若在传感器前插入一块普通玻璃,红外辐射基本上不能透过,可见光可以穿透玻璃,可演示温室暖房原理.The demonstration apparatus for thermal radiation consisting of radiation cube and infrared sensor was introduced. It could demonstrate the influence of temperature, color and roughness on radiant exitance. The Stefan-Boltzmann law and the inverse relation between radiant exitance and the square of distance were explored. The principle of greenhouse was demonstrated by inserting a piece of glass before the infrared sensor, which showed that the visible light could pass through the glass, while the infrared radiation couldn＇t.
